About a year and a half ago, I installed a rebuilt LSD differential on a friends 2002 Ford explorer 4x4. It doesn't see any extreme stress. He regularly takes it to Ford for servicing, and supposedly Ford has been putting the right fluids in.
However recently, it has begin to shudder in turns, and now will not make complete U-turns, and gas mileage is down.
Should they switch to a different oil in the differential? Should they "try" something else to see if it will help the clutch pack to loosen up?
